+Use cases
+---------
+
+There is a collection of some specific recipes which can be found in `the repository <https://github.com/arcan1s/ahriman/tree/master/recipes>`__.
+
+Most of them can be run (``AHRIMAN_PASSWORD`` environment variable is required in the most setups) as simple as:
+
+.. code-block:: shell
+
+   AHRIMAN_PASSWORD=demo docker compose up
+
+Note, however, they are just an examples of specific configuration for specific cases and they are never intended to be used as is in real environment.
